DBB78 - DBB81 F function for positioning axis
Edge evaluation: no Signal(s) updated: cyclic
Signal state 1 or
edge change
0 → 1
The F value of a positioning axis programmed in the current block is entered in the axisspecific PLC
interface signal.
The assignment between the DB number and machine axis number is established using the axis
name.
The value is retained until it is overwritten by another.
Format: Binary number in real format.
Application
example(s)
Modification of the programmed F value by the PLC, e.g. by overwriting the selected axisspecific
feed rate override.
